摘要： A tamper-indicating plastic closure includes a pilfer band at least partially detachably connected to a skirt portion of the closure by a frangible connection. The frangible connection comprises a plurality of circumferentially spaced frangible bridges, which fracture attendant to removal of the closure from an associated container to provide visually discernable evidence of opening. In order to facilitate high-speed application of the closure to a container, one or more regions of the frangible connection are preferentially strengthened by the provision of relatively strengthened frangible bridges. At least one of the strengthened bridges is generally diametrically opposed to the leading portion of the internal thread formation of the closure.

摘要： A tamper-indicating plastic closure is disclosed, with the closure configured for interfering coaction with an associated container. The closure includes a plastic cap having a top wall portion and an internally threaded annular skirt portion, with an annular pilfer band depending therefrom. The pilfer band includes a plurality of circumferentially spaced flexible tabs configured for interfering engagement with an annular locking ring portion of the associated container. The pilfer band further includes an annular interference bead positioned beneath the flexible tabs. By this arrangement, two modes of interfering engagement with the associated container locking ring are provided.
摘要翻译：公开了一种防篡改塑料封盖，封闭件构造成用于与相关联的容器干涉地共同作用。封闭件包括具有顶壁部分和内螺纹环形裙部部分的塑料盖，其中带有环形防盗带。防盗带包括多个周向间隔开的柔性接头，其构造成用于与相关联的容器的环形锁定环部分的干涉接合。防盗带还包括位于柔性突片下方的环形干扰珠。通过这种布置，提供了与相关联的容器锁定环的干涉接合的两种模式。
